How accurate are our Fingerprint Reader offerings?
The accuracy of fingerprint readers has increased dramatically
in the last few years. Error rates have been steadily declining
as matching and sensor technologies evolve. For our
Fingerprint Reader offerings, the False Reject Rate (see
below), given three attempts to validate your finger, is less
than half a percent. The False Accept Rate (see below) is even
lower.
 |
False Non-Match Rate (or False Reject Rate): The
matcher decides there is no match when there is, in fact,
a match. When security is less important and it is
important to do the best you can with only one
measurement, you want a low False Reject Rate.
|
|
False Match Rate (or False Accept Rate): The matcher
decides there is a match when there is, in fact, no match.
When it is really important to be sure that there is a
match, you want to have a very low False Accept Rate. |

If I use a Fingerprint Reader, are my fingerprints secure?
The matching software used by our Fingerprint Reader
offerings does not require much data to recognise a
fingerprint. Using small changes in capacitor resistance, the
reader scans the finger and stores only data concerning
distinctive portions of the fingerprint called “minutia points.”
A complete image of the fingerprint itself is therefore never
stored on the system. The minutia points are only a
mathematical representation of some data from the original
fingerprint. It is not possible to reconstruct the fingerprint
using these points. In addition, these templates are encrypted
when stored. The encryption of the templates does not depend
on Client Security Software. It is an independent element. |

Can fingerprint readers be fooled by hackers?
There are a number of known attacks against fingerprint
readers. Some are rather intricate, such as building a fake
finger out of something like ballistic gel or soft plastic.
Currently, there are no known attacks against capacitive slide
technology, which is what our Fingerprint Reader offerings
are based on. The sensor manufacturers keep on top of these
attacks and continually update their devices to resist them. |

Can I enroll other people to access my computer via the
fingerprint reader?
Several people may share the same PC using the integrated
fingerprint reader. Each user that has a Microsoft® Windows® user ID and password can register up to ten
fingerprints, all of which are stored and associated with that
person’s Windows user ID and password. That means that if
Bob and Alice share a PC, when Bob turns it on and slides his
finger, he gets his desktop. When Alice turns on the PC and
slides her finger, she gets her desktop. |

What happens if the integrated fingerprint reader breaks?
Will I be able to get into my computer?
If the integrated fingerprint reader is not available, prompts
for fingerprint can be by-passed, sending the user to a user
id/password prompt. If the user is protecting data with Client
Security Solution, it will be necessary to use the Client
Security Solution administrative tool to change the policy to
remove the requirement to use the fingerprint reader. Once
that is done, normal use can proceed without the fingerprint
reader. |
